In this work, we address rapid sampling of environmental fields using static and mobile imaging sensors. Specifically, we demonstrate effective reconstruction of the surface temperature field of a patch of vegetation. Accurate monitoring of surface temperature is desirable for various applications, e.g., atmospheric boundary layer studies over complex terrain. We describe an experiment where the surface temperature of a region is observed with a land-based thermal imaging camera, augmented with truecolor images from a parallel-mounted commercial digital camera, and a downward facing non-contact infrared temperature sensor mounted on a quadcopter.
